WET HAIR: Hippies and straights of all ages and coifs congregated at the Delacorte Theater Thursday night for the opening of “Hair.” Although a good portion of the crowd was too young to remember the Summer of Love, a few guests of a certain age waxed nostalgic.

“Oh yeah, I was a hippie, on the Lower East Side,” said Geraldo Rivera, in jeans and a tucked in white dress shirt.

“He would even walk around barefoot,” added his wife Erica Levy, who was born in the Seventies — after the TV host’s walk on the wild side.

Phylicia Rashad, however, couldn’t relate. “I was never into free love,” said the actress. “I couldn’t understand it.”

Undoubtedly, Rashad got a better grip on the counterculture during the outdoor performance, which was punctuated by an as-if-on-cue rainstorm during the finale of “Let the Sunshine In” when the cast and audience alike danced around, soaked but blissful, onstage.

In honor of Rihanna’s 30th birthday, we took a look back at an interview with the Barbados-native when she was just 18 years old. Here, she talked about her second album, “A Girl Like Me” in 2006. “I want to be me. I want people to fall in love with who Rihanna is, and that’s why I want the album to be about me so people can really find out who this girl Rihanna is, because they only know the ‘Pon de Replay’ girl.” Fast forward 12 years, and she’s released six more albums and has become a powerhouse in both the fashion and music industries. Happy birthday, @badgalriri 🎈(📷: Pavel Antonov) #wwdarchive
